How to Get Rid of a Mosquito Problem in Your Yard
|
To get rid of mosquitoes from outside areas so you can enjoy outdoor entertaining, it requires a range of preventative actions as well as mosquito treatments.

Eliminate mosquito breeding sites
Although some species of mosquitoes can fly considerable distances, many species do not move far from their breeding sites. By eliminating breeding sites around the home, we can make a significant dent in the mosquito population.
Mosquitoes tend to prefer still or slow moving water to lay their eggs, so here are the potential breeding sites around your home that you need to remedy…
- Pot plants: Empty any water from the saucers once a week.
- Bromeliads: Empty any water collected in bromeliad leaves once a week (only really practical if they are in pots).
- Puddles: Fill or level areas where puddles form.
- Ponds: Make sure you have enough fish in the any ponds to keep mosquito larvae in check (the common goldfish is pretty good!) and keep vegetation away from the edge of the water.
- Drains: Ensure drains are flowing freely and water is not pooling.
- Gutters: Ensure there is no pooling water and leaves built up in the gutter.
- Rainwater tanks: Rainwater tanks need to have solid, close fitting lids on any access points and mosquito proof meshes on all inlets and overflows (mesh less than 1 mm). This prevents access by adult mosquitoes and also prevents eggs or larvae being washed in from pooled water in the gutter.
- Swimming Pools: Make sure swimming pool chlorine / salt levels are kept up and remove any leaves from the pool.
Outdoor mosquito spray
Adults like to rest in dark, sheltered areas, especially the night biting mosquitoes, which rest during the day. By targeting mosquito resting places with a long lasting residual spray, such as PestXpert Pro-Spray Outdoor Perimeter, it can reduce mosquito numbers to very low levels. Scientific studies have show that such treatments can reduce mosquito numbers by up to 90% for several weeks.
By carrying out a backyard mosquito spray to these resting areas it creates a “mosquito interception zone” which will deal with mosquitoes already in the yard as well as mosquitoes flying in from neighbouring properties.

Here are the top locations to target with your mosquito treatment:
- Under the eaves
- Around any patio and decking (especially under the roof and under the deck)
- Underneath any outdoor furniture (and BBQ)
- In the garage and shed
- Under the house (if you have a sub-floor)
- On the underside of plants around the immediate house perimeter
Make sure the product you use are labelled for these situations, especially when applying to plants. PestXpert Pro-Spray Outdoor Perimeter is an ideal mosquito spray.
These preventative actions and treatments should keep the mosquito population in check so you can enjoy your next BBQ and well-fitting, fly screens will prevent any unwanted visitors inside.
Outdoor Mosquito Repellents
Even with a comprehensive treatment, no external treatment can guarantee 100% control. The use of area mosquito repellents near your outdoor entertaining area can be a good back-up plan, just in case the occasional mosquito wants to gate crash your party. Make sure the product is labelled for outdoor use and generally speaking avoid “natural” products such as citronella, as these have proven to be less effective. Place any product upwind of your gathering, so the repellent is blown into the area to be protected. The wearing of long sleeved shirts and pants or use of personal insect repellents can also be considered.
